(a) The board of county commissioners of any county and the governing body of any city located within the county may enter into a contract providing for the enforcement of the city’s ordinances by the sheriff of the county or other officers of the sheriff’s department. Any contract entered into pursuant to this section shall be submitted to and approved by the county sheriff. Failure of the sheriff to approve a contract within 30 days of its submission shall constitute disapproval thereof. All monetary consideration paid by a city to a county as part of the contract shall be expended by the county solely for law enforcement purposes. The sheriff and any officers of the sheriff’s department assigned responsibility for enforcing a city’s ordinances under the contract shall be designated therein and shall have all the powers of any other police officer of the city by virtue of the existence of the contract.

(b) A contract entered into pursuant to this section shall not be regarded as an interlocal agreement under the provisions of Kan. Stat. Ann. § 12-2901 et seq., and amendments thereto.
